This invention relates to Ynew and, useful improvements in tractors, and tov steeringinechanisins -tl-ierefor.

One objectof'tlie iiiiviitionis to provide a mechanism whereby a tractor may be steered within a short space, thus obviating the use of the usual steering knuckles of the frontaxle.

Another object is to provide means whereby one or the'other of the rear wheels of the 'tractor may be held against rotating,

lwhile the other wheel continues to drive, as

in making a rshort turn.

Other objectsand advantages will be ap- Jarent from the following description when taken in connection with the accompanying drawings. e

ln the drawings:

Figure 1 is a side elevation of a tractor with the present invention applied thereto.

Figure 2 is a front elevation of the saine.

Figure 3 is an elevation of a port-ion of the rear end of the tractor.

Figure 4 is al sectional detail view through one of the brake drums. f

Referring particularly to the accompanying drawings, represents the tractor,

whichhasthe front axle lugs 11, and theA spaced lugs 12, on the lower portion there- Extending forwardly and rearwardly of the tractoigand rockably supported in the lugs 12, is a pin-13, through which is disposed the biglit portion of the V-shaped brace 14.V The forward ends of this brace i. l ordinarily are disposed through'the. vfront axle of the tractor, but in View ofthe fact,v

that the front axle is removed, these lugs are used for another purpose which Vwill presently appear herein.

Disposed vertically in front ofthe radiator 15, of the tractor, is a post 16, andvextending vertically through this post is thel steering post or shaft 17, the lower end of which is provided with the fork 18, while the upper end is provided with the bevel gear 19. A transverse shaft 20 is disposed through the fork or head 18, and mounted Von the ends ofthe shaft are the front ground wheels 21, said wheels being of the saine size as those used on t'liel front axle of the tractor. Extending rearwardly, and slightly downwardly from the upper portion ofthe hollow post 16 are the brace arms 22, the rear ends of which are connected bya bightportion 23, which rests against the upper portion of the radiator 15. From each of particularly 1 vthejbr'ace arms 221 there eXtends-'abrace rod A24,"tlie ,rear end of whichvis properly engaged withga bolt. 25,-"f, .the fraineoff'vthc tractor, as 4clearlyy seen 4in"`*Figure` 1. Ex- .tending rearwardly and downwardly rfrom the lower end of the postA 16 `are the brace arms 26, the lower rear ends of which are connected by the Ib ight portion 27 which is disposed transversely of the tractor, and between the lugs 11, and receives therethrough the usual pivot pin 28. YInclined braces extend from the upper portion of the post 16, as shown at 29, and are connected with the braces 26, atthe lower ends thereof. The forward'ends of the arms of the V-shaped brace 14 are`V connected with the lower ends of the brace arms 26, whereby to provide a rigid structure.

On the upper end of the post 16 there is formed the L-shaped bearing bracket 30, through which is disposed the forward end of the steering'shaft 31, the rear end of said shaft being supported inthe bracket 32. on the rear of the tractor, andV provided with the hand wheel 33. By rotating this hand wheel '33 the shaft 17 will be rotated., and the front wheels'properly steered, and

by reason of the fact that said wheels are shaft 31 is provided'with a bevel gear 34 meshing with the gear 19.

The rear axle housings 35, as well asthe rear axle sections therewithin, are of slightly greater length than those of the ordinary tractor, the traction wheels 36beiiig mounted on the ends of said axle sections, as shown in the drawings, and particularly in Figure 3. rSecured to each wheel is abrake 37, and within the drum is disposed the expanding brake band 38, the ends of tlieband being adapted to be spread by the cam member 39, disposed therebetween. This cam member 39 is provided with a terminal crank arm 40, which is connected with a rod or link 41, said link being-connected with the hand lever 42 in any suitable manner. y

When the tractor is to be steered within a small space, the operator rotates the steering wheel 33 with one hand to turn the front wheels, and at the saine time operates ioo the properlever 42, with the other hand, to f made. Thus the inside wheel will be held` against driving action, while the outside wheel will have :full driving action7 wlierela7 the tractor may be turned in ay small space.

Wliat :is Claimed is:

An extension frame for the front wheels of a tractor comprisingi a vertical post. a rearwardly extending triangularl member carried by tlie upper portion of the post and arranged to engage its base against the ra diator of a tractor, a second triangular frame extending rearwardly and downwardly from the post and having' its base adapted to engage between the front axle lugs of' a tractor.d the ends ot the base of tliie last-named triangular frame being;

apertured for reception ot the ends oli' the usual V-sliaped lira-Ce o'lE a tractor, curved b aces extending' between the post and the second triangular frame, und brace :iran: carried by tlie lirst triangular trarne and extending downwardly and rearwardly for attaeliinent to a part of a tractor.

In testimony whereof, I allix my signature.
